8 11 ÷ 8 9 =	5 8 - 1 2 =	2 3 × 3 4 =	3 5 + 1 2 =
6 7 ÷3=	2 5 × 1 4 =	1 6 + 5 6 × 1 5 =	7 8 ×4× 8 7 =
9 8 ×0=	7 8 ÷ 7 10 =	4 3 ×75%=	7 8 - 3 4 =

Answer 1

考點：分數的加法和減法,分數乘法

專題：運算順序及法則

分析：直接利用分數四則計算的計算法則和混合運算的運算順序計算得出答案即可．

解答：

解： 2 5 + 3 5 =1	1 6 ÷ 1 2 = 1 3	8- 3 4 =7 1 4	6× 1 3 =2
8 11 ÷ 8 9 = 9 11	5 8 - 1 2 = 1 8	2 3 × 3 4 = 1 2	3 5 + 1 2 = 11 10
6 7 ÷3= 2 7	2 5 × 1 4 = 1 10	1 6 + 5 6 × 1 5 = 1 3	7 8 ×4× 8 7 =4
9 8 ×0=0	7 8 ÷ 7 10 = 5 4	4 3 ×75%=1	7 8 - 3 4 = 1 8

點評：掌握計算法則是關鍵，注意計算結果的化簡．
